Application filed March 13, was. (No model.) i

To all whom it may concern:

Be it known that I, LAWRENCE W. COUN- SELMAN, a citizen of the United States, resid ing in the city of Baltimore, in the State of Maryland, have invented certain Improvenients in a Machine for Soldering Cans, of which the following is a specification.

My invention relates to thatvclass of machines which -are. employed for soldering the tops and bottoms; of tin and othernietallic cans so muchusedfor containinglmeats, vegetables, fruits, jellies, and otlier articles of food, and for other purposes.

An advantage that I claim is cheapness in thesolderiug of the cans by the saving of time and laborby means of the simple. mechanism that I haveinvented and employ.

5 To enable alljpersonsversed in the art to. which my invention appertains to readilyunderstand its construction and mode of operation, Iwill nowrdescribe itwith reference to theaccompanyingdrawings, in which- Figure 1 is aftop perspective view of my machine. Fig. 2 is a top plan view with the disk removed. Fig.3 is asectional view through the dotted line 00 y of Fig. 2. Fig. 4. isthe pivoted revolving disk, the pin of which loosely fits into the hole sunk in the bottom or bedplate of the machine.

In Fig. 1 of these drawings I show mymachine in the act of performing its functions. It will be observed that it is higher by a few degrees at the back, whence the flame or heat issues, than in front, into which it is blown, so that the heated current may the more readily pass through after doing its'work. The machine may, for theconvenience of the operator, be placed on a tablcor stand. e I Similar letters refer to similar partsthrough out the several views.

A represents theupper plate, through which passscrews at ae B represents perforations that permit a portion of the flame or heated air to issue from below, and thus heat the part of the can intended to be soldered, 0 being uards to prevent the cans from slipping down the inclined surface. a

G is acircularopening, in which the revolving disk D easily turns when its pin d is inserted in the correspondin g hole, d, in the projection E in the lower plate, F. The pin d has at its end a thumb-scre\v,'d, whereby the height of disk D may be regulated. This lower plate, F, constitutes the bed or bottom part of my machine, and it is closely bolted to or 0th.- erwise firmly united with the upper plate, A, so that the flame or heated air may not find vent atthe joints.

G is an'elevation on plate A, against which the lower-part of the can rests when on the revolving disk D, and H is a guard or rest to.

prevent the can from falling forward- I represents a can before the top is placed on it, and K is a can with the top on, it showing the hole in which is soldereda cap after the can is filled,

It is of course to be understood that,although in the drawings perforations are shown in plate A for but four cans, provision. may be made for any other-desired number. The material best adapted for the making of the principal parts A and F is cast-iron.

Having, as I believe, sufficiently described the construction of the various parts of my invention, I will now describe the modeof operating it. i

The principal parts having been firmly joined and the disk D having been placed in proper position so as to readily revolve on its pivot inserted in the hole in the' lower plate, a flame of gasor other convenient heating medium is blown into the opening at or and partly es capes through a narrow circular Iopening in plate A, outside the edge of said disk D, and is intended to encircle the lower par-t ot the can when it is placed on the said disk. The flame also partly escapes through the perforations B, and finally issues at the vent 'y. The heating apparatus used with the machine is that known as Hills Patent Burner, used for heating purposes, and having a flame spreader attachedto it, so that the heat can be spread fully around the revolving disk. The fuel used is gasoline, street-gas, or equivalent means of 9 5 cility and at such speed as to allow the solder time to fuse and flow to the lower edge. 15y such means the work is done evenly, and the effect of the external flame is to draw the solder through the seam, and practice shows that none or nearly none of the solder is left inside the can, and't'he parts are'fi r'mly seamed and sealed. The work may thus go on continuously, several cans being heated while one is being soldered. The tops and bottoms are a done in the same manner.

the top the cap is must of course be fastened by hand after the can is filled. What I claim, and desire to secure by Letters 15 Patent, is
